Importance of Sustainable Energy in Current Ecosystem

The renewable energy sources are those sources of energy which are inexhaustible and available everywhere in abundance. These energy sources do not cause pollution and are regarded as the ‘clean’ energy sources. More and more countries have turned up towards using these resources i.e. the sun, wind, water, biogas, etc. The costs of sustainable energy sources are also decreasing day by day because of innovations.

The major difference between renewable and the conventional energy forms i.e. fossil fuels is that they are more abundant, diverse with many different options and they can be used anywhere on the planet. The conventional forms emit greenhouse gases leading to global warming which is at present is a major threat. If you see costs, then the price of using sustainable sources are constantly falling because of latest innovations whereas the prices of fossil fuels are soaring high. So many companies started moving towards renewable systems. That’s really a good changeover. Even energy experts like Douglas Healy says that such changeover is expected to maintain equilibrium in the current polluted ecosystem.

Types of Renewable Energy

  • Wind energy– the energy obtained from the wind

  • Solar energy– the energy obtained from the sun. The main technologies used to tap solar energy are solar photovoltaic (using the light from the sun) and solar thermal (using the sun’s heat)

  • Hydraulic or hydroelectric energy– energy obtained from running water i.e. rivers and other freshwater currents

  • Biomass and biogas– energy extracted from organic material

  • Geothermal energy– heat energy from inside the Earth

  • Tidal energy– energy obtained from the tides

  • Wave energy– energy obtained from ocean waves

  • Bioethanol– it is the organic fuel suitable for vehicles and is obtained from fermentation of vegetation

  • Biodiesel– it is also organic fuel for vehicles and obtained from vegetable oils

Advantages of Clean Energies

  • Helps fight against climate change– the renewable energy sources are called clean energies since they do not emit greenhouse gases in energy generation processes. Thus they can play a vital role in preventing our environment from pollution.

  • Inexhaustible form of energy– the conventional energy sources like coal, gas, oil are finite and once used can’t be replenished. Whereas the sustainable energy sources such as wind, water, sun is inexhaustible. They will always be available that is why everyone is seeing it as a most promising future energy source.

  • Reduced energy dependence– more and more use of clean energy sources has lessened our dependence on the non-renewable sources of energy. Earlier countries had to import fossil fuels which added to their economic burden and they found it difficult to meet even the short-term energy goals. But with renewable energy sources wind, water, sun, biomass you need not to take them from anywhere else, they are already present everywhere in abundance.

  • Highly competitive– The main renewable technologies like wind and solar photovoltaic are drastically reducing their costs so that they can compete with the conventional sources of energy. More and more countries are making them self-sufficient in their energy needs with the help of these sustainable energy sources. And with more and more innovations taking place in this field which is making it economically sustainable.

  • Favorable political horizon– the benefits of various decisions from different countries worldwide is directly have on more and more use of sustainable energy sources. Decisions adopted at COP21 have shone the spotlight on renewable energies.  The international community has stood firmly for the transition towards a low-carbon economy in order to guarantee a sustainable future for our mother earth. International consensus has reached in favor of the “de-carbonization” of the economy. All these developments have led towards constituting a very favorable framework for the promotion of clean energy technologies.

International Energy Agency (IEA) has stated in its report that the world electricity demand will increase by 70% by 2040. Its share of final energy use rising from 18 to 24% during the same period mainly because of use by the emerging economies of India, China, Africa, the Middle East and South-East Asia.

Using clean energy is vital for combating climate change and limiting its most devastating effects. The report mentions that some 1.1 billion inhabitants (17% of the world population) do not have access to electricity. Around 2.7 billion people (38% of the population) use conventional biomass for cooking, heating and lighting in their homes, at serious risk to their health. Because of this one of the objectives established by the United Nations is to achieve to access to electricity for everyone by 2030. This is an ambitious target considering that, by 2030; according to the estimates 800 million people will have no access to an electricity supply if current trends continue.
